WATER-SUPPLY VALVE.

SPECIFICATION forming part of Letters Patent No. 238,504, dated March 8,1881.

Application filed June 18, 1880.

To all whom it may concern Be it known that I, PATRICK HARVEY, ofChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Water-Supply Valves; and I herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which myinvention appertains to make and use the same, reference being had tothe accompanying drawings, forming a part hereof, in which- Figure 1represents a vertical central section, with the valves in position forsupplying Fig. 2 represents the same with the valves closed against themain or supply, and discharging the water above the same into the waste.

Like letters of reference indicate like parts.

The object of my invention is to provide a water-supply valve forwater-pipes and hydrants tha may readily and easily be operated from anydesired place, and which shall be less liable to wear and consequentleakage than the check and waste stop-cock commonly used; and myinvention consists in combining with a water-supply or main valve,acheckvalve which controls the operation or action of the main valve bymeans of the water-pressure, substantially as herein shown anddescribed.

In the drawings, A represents the casin gformingthe chambercontainingtheoperating parts, to the lower end of which is screwed a cap, 0, providedwith an inlet or induction, T, and to the upper end is screwed a cap, B,provided with a chamber containing the valve and a tubular stem, N,through which passes the stem of the valve W, to thelower end of whichis attached a valve, k, provided with a packing, 0, to fit against thevalve-seat k at the lower end of the tube N. The opening of the chamberof the valve k is closed by a rubber diaphragm, f, and said diaphragm isheld in place by the cap B screwed upon it, as shown. Through the cap Bpasses a stem, L, the lower end of which is provided with a broad footresting upon the diaphragm f. The casing A is also provided with anoutlet or eduction, a, to which the pipe furnishing the supply isattached, and a waste, R, to which the pipe for conducting away thewaste is attac'hed.

(No model.)

Within the casing A is a main valve, G, provided with wings or guides aat its lower end, which guide and hold itin place in its motions throughthe guide-plate F and leather packing a, and a stem, H, provided with awater-way, M, and a flange near its upper end, on which rests thepacking e, forming a valve which moves through the contracted part ofthe casing or chamber A, as shown.

To the upper end of the hollow stem H is screwed a short tubular stem,which securely holds the packing c in place, and forms a chamber for thevalve k to play in, and large enough to leave afree water-way around it.To the outside of said stem is secured a flange, I, upon which rests apacking, d, and upon the top thereof is a packing, 6, working against N.Both of the packings I) and cl are held in place by the cap J screwedupon the upper end thereof.

The cap B is also provided with a small tubular opening, 9, leading fromthe chamber of the valve k to an annular groove, 8, and said groove 8 isopposite a corresponding groove, 8, in the upper end of the casing A,and between the casing A and cap B is placed an annular washer, h, forthe purpose of securely packing the joint; and at intervals holes orslots t are out through said washer it, so that water passing from thechannel 9 into 8 may find its way through the openings 11 into theannular channel 8, with which the vertical channel 9 is connected, anddischarges into It. The object of the annular channels 8 s and holes 2'in washer his to afi'ord a passage for the water into g, no matter atwhat point the outer end of channel 9 may stop when the cap B is screwedupon A.

Near the base of the hollow stem N is a small orifice, 0, which opens awater-way from M through It into the chamber 1).

To the cap B is also attached a forming the fulcrum of the lever D.

To lever D 1s attached a weight, E, and connecting-wire 2, which, at itsother end, is attached to a weighted lever, WV, which is both jointedand pivoted at Y, and said lever W is arrested in its motions around Yby stops to x, as shown. The lever D of Fig. 2 is shown depressed, andthe lever W and wire z are shown dotted, the wire 2 being shown brokenaway post B from the depressed lever, and the end pointed in thedirection indicating the position described and shown in Fig. 2.

The operation of my improved water-supply valve is as follows, to wit:Into any convenient part of the house, preferably at the spigot over thesink, is attached to the wall, the weighted lever W, from which, bymeans of the wire or wiresz, provided with bell-cranks in the usualmanner, the weighted lever D of the stop-valve, placed in the cellar orunder ground far enough to be secure against frost, is reached. Thesupply-pipe from the main is secured to the cap 0, the distribution-pipeto the outlet to, and a waste-pipe, connecting with a drain, to thewaste It. \Vhen the lever W is turned into the position shown in dottedoutline in Fig. 2 it causes the lever D to press the" valve k onto itsseat, and thereby open the passage or water-way through L from M, andthence through 0 into the chainberp, and, by the pressure derived fromthe head of the supply produced therein, moves and holds the valves(1,6, and G in the position as shown in Fig. 2. \Vhen the lever W isturned into the position as shown in Fig. 1, it raises the lever D,which thereby relieves the pressure upon the valve 73, which is thencaused to rise by the water-pressure, and a current of water is at onceformed from M through 9, which, by means of its motion, carries thevalve It: with it against its seat and holds it, thereby instantlyclosni g the passage through 7;, and so takes away the water-pressure inthe chamber 1), and consequently relieving all downward pressure uponthe valve G, which, being acted upon by the pressure from the mainthrough T, is raised, as shown, opening the channels for the water-su 'iiily, indicated by the arrows to. \Vhen it is desired to shut oli' thesupply from the house, the lever Wis turned into the position which thenreleases the weighted lever D, the weight E of which is made heavyenough to overcome the upward pressure of the water on It, which thendepresses the stem L, diaphragm f, and valve k until it rests upon itsseat in the cap B, thereby closing the channel g, and forcing the valvek to open against the pressure of the water, and thus form a currentfrom M through 7c into N, and through 0 into the chamber 1), which, asis shown, is

considerably larger in end area than that of the valve G, andconsequently when so arranged will press with greater force upon thearea of the piston 01 and cap J than against the piston. G, andconsequently cause it to descend until the piston G closes the inlets uand is arrested in its descent by the flange I, resting upon theshoulder formed in the easing A by the smaller bore thereof for thepiston c, and the piston e passing below the lower end of its chamber orbore allows a free exit of the water around it from u through the wasteIt, as shown by the arrows r. The water entering the chamber 19, asshown by the arrow m, and receiving its pressure direct from the main,will hold all parts in the position as shown in Fig. 2, until the weightE is raised, as previously explained, when the valve is will at onceclose and raise the valve k which opens an outlet from the chamber 12through 0 g s 'i s It, through which it is emptied as the pistons G, e,and d are caused to rise by the pressure of the water from the mainagainst the piston G, which opens the water ways or inlets, as shown bythe arrows it.
